9-3 Rewriting Radical Expressions – We practiced using the properties of exponents to rewrite radical expressions. Then we multiplied radical expressions. Next we learned to write a radical expression to model or represent a real-world problem. We practiced writing radical expressions in simplest form which is where there are no perfect square factors other than one in the radicand.

9-2 Solving Quadratic Equations by Factoring – We practiced using the Zero-Product Property and factoring to find the solutions of a quadratic equation. Then we calculated the vertex. Next we used the zeros of a quadratic equation and the vertex to sketch the graph. Next we reviewed how to write the factored form of a quadratic function from the graph.
9-3 Rewriting Radical Expressions – We learned about radicals, radical expressions, and perfect square factors.

9-1 Solving Quadratic Equations Using Graphs and Tables – We reviewed how to use a graph to identify the x-intercepts as solutions of a quadratic equation. If the graph of the function has no x-intercepts then the equation has no real solutions. If the graph touches the x-axis but does not cross it then there is only one x-intercept and one real solution. Next we practiced finding the vertex of the parabola by putting the equation in the form ax2 + bx + c and calculating the x-coordinate by the formula –b/2a and
we found the y-coordinate by using the formula –b/2a. Next we plugged the x-coordinate of the vertex into the original quadratic equation to find the y-coordinate of the vertex. Bella did some practice problems to ensure that she is prepared to do her homework.

9-5 Completing the Square – We reviewed that Completing the square is a method that is used for converting a quadratic expression of the form ax2 + bx + c to the vertex form a(x - h)2 + k. The most common application of completing the square is in solving a quadratic equation. This can be done by rearranging the expression obtained after completing the square: a(x + m)2 + n, such that the left side is a perfect square trinomial. Completing the square method is useful in:
• Converting a quadratic expression into vertex form.
• Analyzing at which point the quadratic expression has minimum/maximum value.
• Graphing a quadratic function.
• Solving a quadratic equation.
• Deriving the quadratic formula.

8-3 Quadratic Functions in Standard Form – We learned to compare properties of quadratic functions. We found the x coordinate by using the formula –b/2a. Next we plugged the x value into the equation to find the y value. Then we applied these principles to real-world problems.
